3 Device description
The recooling system comprises the four main components:
evaporator (12), compressor (13), condenser
(1) with fan (2) as well as the control or expansion
valve (4), which are connected together by
pipes. A pressure switch (14) limits the maximum
pressure in the refrigerant circuit. The R134a
(CH2FCF3) refrigerant is free from chlorine. Its
Ozone Depletion Potential (ODP) is 0.
A filter dryer (3) which is integrated into the hermetically
sealed refrigerant circuit provides effective
protection against moisture, acid, dirt particles, and
foreign bodies. A temperature control with temperature
probe (6) ensures that the cooling medium is
maintained at a preset setpoint temperature.
In the evaporator (12), the liquid refrigerant is converted
to a gaseous state. The heat necessary for
this purpose is taken from the cooling medium in the
plate heat exchanger, which has the effect of cooling
the cooling medium. The refrigerant is heavily
compressed in the compressor (13). As a result the
refrigerant has a higher temperature than the ambient
air. This heat is dissipated to the ambient air
over the surface of the condenser (1), resulting in
the refrigerant liquefying again.
The refrigerant is injected into the evaporator (12)
using a thermostatic expansion valve (4), as a result
it is expanded and is therefore able to absorb the
heat from the cooling medium (water, water-glycol
mixture).
The cooling medium is pumped to the equipment in
a closed circuit using a pump (9) and cooling medium
tank (10). The flow switch (11) ensures the
evaporator (12) is protected against freezing if the
flow rate is too low. The level switch (5, optional)
protects the pump (9) against dry running. The cooling
medium (water or water-glycol mixture) feed
temperature is regulated using the temperature
probe (6) in the tank.
You will find the flow diagrams for the individual
types of units in chapter 13.
3.1.1 Controller
The recooling units are fitted with a controller for
setting the functions of the recooling unit. Operating
states are displayed using a display unit and parameters
can be set using buttons.
Page 7 of 61
EN

3.1.2 Safety devices
The recooling unit has a pressure switch in accordance
with EN 12263, tested at component level, in
the refrigerant circuit; this device is set to the maximum
permissible pressure (PS). An automatic reset
device ensures that the system continues to work
after the pressure drops (autoreset).
Temperature monitoring prevents the evaporator
coil from icing over. If there is a risk of icing, the
compressor switches itself off and automatically
switches itself back on again at higher temperatures.
The refrigerant compressor motor and the fan motors
are equipped with thermal winding protection
switches against excess current and excess temperatures.
To ensure that the compressor runs reliably and
without problems (for example after reaching the
setpoint temperature or after a fault), the compressor
automatically switches back on after a delay of
180 seconds.
The recooling unit has two integrated floating fault
signal contacts (see circuit diagram of the relevant
unit type, sections 13.4 and 13.5). Individual fault
messages can be interrogated via an integrated
Sub-D socket using an external PLC controller.
3.1.3 Filter mats
If there is coarse dust and fluff in the ambient air, we
recommend fitting an additional filter mat (available
as an accessory) in the recooling unit (provision has
been made for installation). You will need to replace
the filter regularly depending on the amount of dust.
For air that contains an oil mist, we recommend
metal filter mats (accessory). These may be cleaned
with suitable detergents and reused.
Automatic filter mat monitoring is built into recooling
units (turned off by default). The device measures
the dirt in the filter mat by comparing the ambient
temperature and the air output temperature on the
condenser. As the filter mat becomes increasingly
dirty, the pressure in the refrigerant circuit rises and
with it the temperature of the output air. This results
eventually in a fault message.
3 Device description
3.2 Proper use
Rittal recooling units have been developed and designed
in accordance with the state of the art and
the recognised rules governing safety. Nevertheless,
if used improperly, they may pose a threat to
life and limb or cause damage to property.
The TopTherm recooling units described in these
instructions must only be used for cooling water or a
water-glycol mixture.
If using other fluids (e.g. de-ionised water), please
refer to the technical specifications contained in the
appendix, or contact the manufacturer. Under no
circumstances should the limit values specified in
the technical specifications be exceeded.
Explosion hazard!
The use of the recooling unit for cooling
inflammable or explosive substances is
prohibited.
3.3 Supply includes
The unit is supplied in packaging in a fully assembled
state.
Please check the scope of supply for completeness.
Check the packaging carefully for signs of damage.
Traces of oil on damaged packaging indicate a loss
of refrigerant. The unit may have leaked. Any packaging
damage may be the cause of a subsequent
functional failure.

4 Transportation
For water cooling medium:
If the recooling system is stored or transported at
temperatures below freezing, you must completely
drain the cooling medium circuit and flush it with a
water-glycol mixture to prevent frost damage. This
instruction also applies to the external condenser
circuit for a water-cooled condenser (option).
Only transport the recooling unit in its original packaging
material before commissioning for the first
time. In case of damage, inform the manufacturer
without delay.
When transporting the recooling unit, the weight
specified on the rating plate must be taken into consideration.
Use lifting gear with an appropriate minimum load
capacity.
To prevent transport damage to the unit, proceed as
follows:
Only transport the unit in an upright position.
Fig. 11 Eyebolt for transportation (331x.6xx shown here as
an example)
Only transport the unit on the pallet supplied with
the unit or with the eyebolt provided (1).
Prevent excessive vibration.
If it is necessary to move the unit in the factory, you
must disconnect all connections on the unit.

5.2 Installation site requirements
The site must be free from excessive dirt and moisture.
The ambient temperature must not exceed 43°C.
Install the recooling unit close to the equipment
being cooled to avoid long distances and related
performance losses.
Performance losses arise in particular due to:
Pressure drops in the refrigerant piping system
caused by resistance in the pipes and individual
components such as shut-off valves and pipe
bends.
Heat transfer in uninsulated pipes.
Select the installation site such that:
Easy access is possible at any time. This situation
will ease maintenance and repair.
The condenser fan does not operate in a "shortcircuit",
whereby the warm exhaust air from the condenser
is drawn in again by the condenser's fan.
An "air short-circuit" will result in a loss of performance
of the recooling unit.
Maintain the following minimum distances (in mm)
from the wall:

AIR OUT
AIR IN
300
300
Note!
For unit types 3318.6xx and 3319.6xx,
the airflow passes through the unit from
front to back.
With unit types 3320.6xx and 3334.6xx
the airflow passes through the unit from
back to front.
Ensure the room is adequately ventilated by installing
the recooling unit such that the heat dissipated
by the unit does not heat the room excessively.
The ambient temperature will increase due to the
heat dissipated. This temperature increase may
cause a loss of performance of the recooling unit.
In case of installation in a "small" room, it is imperative
that you provide forced ventilation, as otherwise
the heat dissipated will build up.
The connection of ducts for fresh and exhaust air to
our devices is not suitable, as these units are
equipped with axial fans and these cannot build up
the necessary additional air pressure.
To prevent performance losses, do not install the
recooling unit near any form of heating.
Outdoor siting
Cooling units must be installed such that they cannot
become damaged by internal traffic and transport
operations.
Page 15 of 61
EN

5.3 Installing the recooling unit
Install the recooling unit on an even, firm surface.
The maximum permissible deviation from the vertical
is 2°.
Avoid the production of noise due to vibration (vibration
dampers, sheets of foam rubber).
5.4 Making the hydraulic connection
Caution!
Risk of damage to the circulation pump
due to soiling in the cooling medium
circuit! Flush the cooling medium circuit
prior to connecting to the recooling unit.
The cooling medium outlet on the recooling unit (see
(6) Fig. 2 or (9) Fig. 4) must be connected to the
cooling medium inlet on the equipment to be cooled.
The cooling medium inlet on the recooling unit (see
(8) Fig. 2 or (10) Fig. 4) must be connected to the
cooling medium outlet on the equipment to be
cooled.
Use only insulated pipes and/or hoses to connect
the equipment to the recooling unit.
The nominal size of the piping must be at least the
same as the nominal size of the medium connections
on the unit, and on pressure-sealed units must
be approved for the maximum pressure expected,
see chapter 11.
Note!
The use of steel pipes or galvanised steel
pipes is inadmissible.
For pressure-sealed units (3318.6xx and 3319.6xx)
Install a pressure manometer, 0 to 6 bar, in the cooling
medium circuit.
For types 3320.6xx, 3334.6xx and 3360.47x only:
Prior to commissioning, it is imperative that the cooling
medium pump is filled with cooling medium and
bled, see chapter 6.
In the case of a water-cooled condenser (optional),
the operator must:
Make the cooling water connections.
Caution!
Risk of damage for the unit!
Insufficient pressure (on pressure-sealed
units) and an excessively low flow rate
will trigger the safety devices in the unit.
Pay attention to the required minimum
pressure and the minimum flow rate, see
chapter 11.
5 Assembly and connection
Only for types 3318.61x, 3319.61x, 3320.6xx,
3334.6xx, 3334.66x, 3360.xxx that are open to the
atmosphere:
If the cooler on the equipment to be cooled is higher
than the recooling unit, we recommend installing a
non-return valve in the feed as well as a solenoid
valve in the cooling medium circuit return to prevent
the tank from overflowing.
Caution!
Risk of damage for the cooling medium
pump due to dry running! If it is possible
to shut off the circuit to the equipment to
be cooled, you must install a bypass
valve (can be ordered as an option) between
the feed and return to protect the
cooling medium pump.
Page 16 of 61
EN

5.5 Making electrical connection
It is imperative that you follow the instructions
given below:
When carrying out the electrical installation, observe
all applicable national and regional regulations as
well as the regulations from the responsible utility
company. Electrical installation must only be carried
out by a qualified electrician who is responsible for
compliance with the existing standards and regulations.
The voltage and frequency of the connection must
correspond to the values stated on the rating plate.
The recooling unit must be connected to the mains
via an all-pole isolating device.
No additional temperature control is allowed to be
connected upstream of the recooling system on the
supply side.
Install the pre-fuse cited on the rating plate (miniature
circuit-breaker "K" characteristic or slow fuse) to
protect the cable and equipment from short-circuits.
The mains connection must ensure low-noise potential
equalisation. Recooling units must always be integrated
into the building's equipotential bonding
system.
The conductor cross-sections of the power cable
must be selected according to the rated current (see
rating plate).
The recooling unit does not have its own overvoltage
protection. Measures must be taken by the operator
at the supply end to ensure effective lightning
and overvoltage protection. The mains voltage must
not exceed the tolerance of +6/-10 %, see chapter
11.
On three-phase units: The connection must be
made with the field rotating clockwise. The direction
of rotation of the field can be measured at the connection
terminals L1, L2 and L3. Connection with a
clockwise rotating field ensures that all three-phase
motors rotate in the correct direction.
In case of an integrated transformer (optional): Ensure
correct voltage connection on the primary side.
If you want to evaluate the fault codes for fault signals
from the recooling unit using the alarm relay,
you must also connect an appropriate low-voltage
cable to terminals 3 – 8, see circuit diagram for the
relevant unit type in chapter 13.
If the recooling system requires remote switching,
terminals 1 and 2 can be used for this purpose (see
the circuit diagram for the relevant unit type in chapter
13) together with the appropriate programming
(parameter 18), see chapter 7.4.
5 Assembly and connection
5.5.1 Connecting the power supply
The units are prewired ready for connection in the
factory and equipped with a twelve-wire connection
cable (length 2.5 m).
Make the electrical connection as per the electrical
circuit diagram (see circuit diagram for the relevant
unit type in chapter 13).
5.5.2 Connecting the alarm relay interrogation
device
You can also query fault messages with two floating
contacts on a separate connection clamp of the
recooling unit. The necessary wires are already
present in the connection cable and are connected
in the device.
Connect the correspondingly labelled wires of the
connection cable to the controller as shown in the
electrical circuit diagram (see circuit diagram for the
relevant unit type in chapter 13).
For details on the assignment of alarm relay contacts
when an error code is displayed, see section
7.6.
5.5.3 External activation (option)
The unit has been prepared with the option for control
via an external signal. To implement this, the

6 Commissioning
The recooling unit does not have its own main
switch to switch the recooling unit on and off. It must
be switched on and off by the higher-level controller.
6.1 Antifreeze
As standard, the units are not suitable for operation
below the specified minimum temperature (see
chapter 11). The units are always to be used with a
water-glycol mixture for the coolant with a maximum
glycol content of between 20 and 30% by volume.
The recommended antifreeze is Antifrogen N or our
Rittal Rifrost.
Other types of antifreeze are possible in specific
cases, however only in consultation with the manufacturer.
Note!
Only use distilled or de-ionised water in
recooling units specified for such use (see
chapter 11).
Caution!
Risk of damage for pipes and seals!
Other additives may damage the pipes
and the seal on the cooling medium
pump and are therefore not allowed.
To prevent problems in the cooling medium circuit
(also water-cooled units), it is imperative that the
VEB Cooling Medium Guidelines (VGB-R 455 P) are
observed.
You can read and determine the correct glycol content
with the aid of a refractometer, available from
the following supplier: Georg Pforr -gefo- GmbH &
Co. KG, Holterkamp 16, D-40880 Ratingen, Germany.
http://www.gefo.de.
6.2 Filling the recooling system with
cooling medium
The composition of the cooling medium is described
in chapter 8.
For commissioning, proceed as follows:
Ensure that any shut-off valves installed in the cooling
medium circuit are open.

the actual feed temperature of the cooling medium.
Check the direction of rotation of the motors (see
direction of rotation arrows on the cooling medium
pump and on the condenser fan).
Note!
If the compressor and condenser fan do
not start to operate, the temperature of the
cooling medium added is lower than the
setpoint temperature set.
If necessary, lower the setpoint temperature momentarily;
see section 7.4.
Page 20 of 61
EN

7 Operation
The recooling unit is switched on and off by the
higher-level control. It operates automatically, i.e.
the cooling medium is pumped continuously and
heat extracted from it during this process.
A controller provides automatic control based on the
hysteresis set. The controller has a display for the
indication of temperature values and buttons for
setting operating parameters.
7.1 Controls
Fig. 29 Controls – controller
Key
1 7-segment display
2 Temperature unit LEDs
3 Control keys
The units have a 3-digit 7-segment display to indicate
operating states and control keys to set operating
parameters.
After the power supply is switched on, the display
"E0" appears initially for approx. 20 seconds to indicate
that the unit is operational (boot phase controller).
After the boot phase, the chiller will start to
work.
During operation, the inlet temperature (to the
equipment) of the cooling medium circuit is displayed
via the indicators, alternating with any error
messages that are present in the form of error
codes; see section 7.5. Two LEDs °C and °F are
used as indicators for the temperature unit °C (Celsius)
or °F (Fahrenheit).
You can perform the following activities via indicators
and control keys:
Reading temperature values
Reading from error memory
Acknowledging error messages
Resetting the pump
Reading and setting parameters for the controller
The measurement range for temperature measurements
is:
Celsius: –40°C to 70°C
Fahrenheit: –40°F to 158°F
Temperatures are shown with a resolution of 0.1° in
the following ranges:

7.8 Setting the digital real-time clock
The micro controller box is fitted with an integral
real-time clock. The current time can be set in menu
P9 under "Time". It is also possible to switch between
summer time and winter time. The clock is
supplied with power by a lithium battery.
Clock control can be switched on and off and parameterised
separately for cooling (P10, "Switching
times, compressor") and heating mode (P11,
"Switching times, heater"). If clock control is deactivated
(P10 or P11, "OFF"), control occurs independently
of the time. If clock control is activated
(P10 or P11, "ON"), control only operates within the
preset time intervals.
The time intervals may be set individually for each
day of the week with a start time (hour/minute) and

8.1 Maintaining the refrigerant circuit
As a hermetically sealed system, the refrigerant
circuit has been filled in the factory with the required
amount of refrigerant, tested for leaks and subjected
to a function test run.
Maintenance tasks on the refrigerant circuit must
only be undertaken by a specialist refrigeration
company. We recommend a maintenance contract
that includes an annual inspection of the refrigerant
circuit (European regulation EC No. 842/2006 /
fluorinated greenhouse gases).

8.2 Water quality
In case of cooling of/with water + glycol or similar
fluids in the open circuit, always observe the following
points:
Regularly clean solid residues (from any filters
used),
Algae and deposits, as well as
Corrosion,
can cause damage to the recooling unit. Residues
will always impair the performance of the recooling
unit. Without water treatment it is seldom possible to
achieve satisfactory conditions. By means of regular
monitoring of the quality of the cooling medium and
cooling medium treatment, you must ensure that
deposits and corrosion are avoided, even under
extreme conditions.
There are specific cooling medium requirements
depending on the type of equipment being cooled. A
suitable process must then be used to prepare
and/or maintain the cooling medium to suit the level
of contamination and the size and design of the
recooling system. The most common types of contamination
and most frequently used techniques to
eliminate them in industrial cooling are:
Mechanical contamination:
Filtering of the cooling medium via mesh filter,
gravel filter, cartridge filter, or pre-coated filter
Excessive hardness:
Softening of the cooling medium using ion exchange
Moderate content of mechanical contaminants
and hardeners:
Addition of stabilisers and/or dispersing agents to
the water
Moderate content of chemical contaminants:
Addition of passifiers and/or inhibitors to the cooling
medium
Biological contaminants, slime bacteria, and
algae:
Addition of biocides to the cooling medium
Note!
The cooling medium thickens due to
evaporation. You can return the values
to within the usual ranges by completely
replacing the cooling medium. Only use
distilled or de-ionised water in recooling
units specified for such use (see chapter
11).
The manufacturer's guarantee and liability will be
rendered void in cases of incorrect use and treatment
of the recooling unit.
To prevent problems in the coolant/heat transfer
circuit (also on water-cooled units), it is imperative
that the VEB Cooling Water Guidelines (VGB-R
455 P) are observed (for source, see chapter 12).
Portion of antifreeze in the cooling medium, see
chapter 11.
8 Inspection and maintenance
The cooling medium and/or cold water must not
cause any limescale deposits or loose debris.
In other words, it should have a low level of hardness,
particularly a low level of calcium hardness. In
particular, the level of calcium hardness should not
be too high when using the equipment for recirculated
cooling. On the other hand, the cooling medium
should not be so soft that it attacks the materials.
When recooling the cooling medium, the salt
content should not be allowed to increase excessively
due to the evaporation of large quantities of
water, since the electrical conductivity will increase
as the concentration of dissolved substances rises,
and the cooling medium will become more corrosive.
For this reason, not only is it always necessary
to add a corresponding quantity of fresh water, but
also to remove part of the enriched cooling medium.
Hydrological data
The properties of the water used should not deviate
from the hydrological data listed below.
The local drinking water values are to be noted.

Note!
To be 100% certain the water quality
is appropriate, we recommend the
usage of "Rittal Rifrost". This is a
ready-to-use mixture that can be used
straight away.
Distilled or demineralised water may only be used in
recooling units that have been specified for this
purpose.
Rittal recommends the use of "Rifrost" (Rittal readymix)
or Antifrogen N by Clariant as a concentrate.

8.3 Cleaning the condenser
Risk of electric shock at live connections!
Prior to inspection and maintenance
work, electrically isolate the recooling
unit from the electrical supply.
The entire condenser is covered in a dirt-repellent,
easy-to-clean RiNano coating. In many applications,
therefore, the use of filter media is unnecessary,
particularly with dry dusts.
To ensure the correct function of the recooling unit,
the fins on the air-cooled condenser must be kept
clean. Cleaning must be undertaken at regular intervals
of at least once a year; the frequency of cleaning
depends on the degree of soiling in the rooms
where the unit is installed.
Risk of injury due to sharp-edged condenser
fins! Use gloves as personal
protection equipment.
The hot gas pipe inside the unit can
reach a temperature of approx. 60°C.
Wait approx. 10 min. after you have
switched off the unit to allow the pipe to
cool down.
Fig. 30 Cleaning the condenser (shown here: 3320.6xx
and 3334.6xx)
Deactivate the unit by switching off the power supply
to the higher level control and secure against
switching back on.
Remove the louvred grille (2) Fig. 30 on the front of
the recooling unit.
Caution!
Risk of damage for the condenser fins
due to powerful compressed air!
Use the compressed air carefully to
avoid damage.
Clean the condenser (1) Fig. 30 with compressed
air.
8 Inspection and maintenance
Ambient air containing oil:
Ambient air containing oil in conjunction with dust
will result in increased soiling of the condenser fins.
Thorough cleaning with compressed air is not possible
in this case.
We recommend sending the unit in for cleaning or
requesting service.
8.4 Cleaning the filter mat (optional)
For types 3318.6xx and 3319.6xx:
Danger of injury due to rotating fan
blades!
Do not remove the louvred grille until
after the condenser fan has come to a
stop.
Remove the louvred grille on the front of the recooling
system by carefully pulling it off the housing.
The louvred grilles are fastened onto the housing
with plastic pins.
Remove the filter mat from the louvred grilles.
Replace the filter mats made of filter fleece. Clean
the metal filter mats with a high-pressure cleaner.
Place a new filter mat or the cleaned metal filter mat
in the louvred grille and press it back onto the housing.
Fortypes 3320.6xx and 3334.6xx:
The louvred grilles are fastened onto the housing
with plastic pins.
Danger of injury due to rotating fan

10 Shutting down and disposal
The recooling unit must only be shut down by
authorised, qualified personnel. For this purpose the
unit must be decommissioned.
Electrically isolate the unit at the mains isolation
device.
10.1 Shutting down for an extended
period
If the recooling system will not be used for an extended
period (more than 6 months) the cooling
medium circuit must be drained to prevent the
evaporation of water and to prevent a change in the
water-glycol ratio in the cooling medium. If the glycol
concentration increases, the pump seal may be
irreparably damaged.
Isolate the unit from the supply of power and secure
it against switching back on.
Disconnect the cooling medium circuit connections.
Drain the cooling medium circuit, see chapter 8.
For disposal of the cooling medium, observe the
applicable regulations on water pollution, in Germany
the Wasserhaushaltsgesetz (Federal Water
Act).
To recommission the recooling system, proceed as
described in chapter 6. Make the same checks as
described in that chapter.
10.2 Shutting down and disposal
Attention, risk for the environment!
Intentional release of the refrigerant
is strictly prohibited. Refrigerant

13.8 Accessories
Overflow valve
Pressostat for use in the water cycle between the recooling system and the air/water heat exchanger.
It prevents an increase in pump pressure in the recooling system against the closed
magnetic valve of the air/water heat exchanger outside of the cooling cycle.
Material: Brass. Setting range: 2 – 12 bar. Presetting: 3 bar
Version Packs of Model No. SK
1/2˝ bypass valve 1 3301.900
3/4˝ bypass valve 1 3301.910
1˝ bypass valve 1 3301.920
13 Appendix
Flow regulator valve
For use with air/water heat exchangers, especially if more than one heat exchanger (n > 1) is
used in the water cooling circuit. The correctly set valve then ensures the same quantity of cooling
medium for all equipment. The valve is used for hydraulic balancing.
Material: Brass. Setting range: 3 – 12 l/min
Version Packs of Model No. SK

Metal filter
Particularly when chiller units are used in dusty and oil-laden environments, it is advisable to use
washable metal filters. If air or steam condenses on the metal surfaces, any particles that may be
present will adhere to the metal and are easily washed out with water or grease-dissolving detergents.
